To all whom, t may concern.'

Be it known that we, JULTUS J. MOJON- Nnin, HARLEY R. PHILLIPS, and HENRI B. WARREN, the latter deceased, Lnwis W.

WARREN being the administrator of his estate. all citizens of the United States, and residents of Oak Park, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Clutches,

of which the following is a specification.

This invention relates to clutches gener-v ally and the particular form of the invention disclosed herein was devised for use inan ice cream ackaging machine. The principal object of t ie invention is to provide a clutch which will work efiiciently in a packaging machine of the class mentioned. Theinvention consists in the construction, combination and arrangement of parts as hereinafter fully described and claimed and as fully illustrated in the accompanying drawings wherein F ig. 1 is a plan view of a clutch and control constructed and arranged in accordance with the present invention.

Fig. 2 is an enlarged plan view of a portion of the same, illustrating more particularly the clutch.

Fig. 3 is a side elevation of the clutch of Fig. 2 with parts broken away.

Fig. 4 is a horizontal section showing the clutch pin in clutching position, the plane of section being indicated by the line 4 4 of F ig. 3.

Fig. 5 is a vertical section of the same, the plane of section being indicated by the hne 5-5 of Fig. 2.

Throughout these views like characters refer to like parts.

The present application is a division of our prior application Serial No. 574,642, filed June 13, 1922, Patent No. 1,502,314, dated July 22, 1924.

Referring to the drawing 1n detail, 113 designates la constantly rotating gear wheel which is driven through a beveled pinion 114 on the drive shaft 109 which, in turn, is constantly driven from some suitable source of power. The wheel 113 is loosely mounted upon the shaft 111 and the latter is suitably mounted in a yoke 112 of the machine. In the operation of the packaging machine it is necessary to drive the shaft 111 at intervals from the wheel 113. This is accomplished by a clutch interposed between the wheel 113 and the shaft 111 which is under the control of cartons or containers C upon a rotating table 78. The latter is advanced by ratchet mechanism (not shown) operated from an' eccentric formed integrally with the gear wheel 1 13 on its under face. The eccentric 115 is encircled by an eccentric band 116 attached to the ratchet operating rod 94 by a socket 117. The clutch collar 139 is fixed to the shaft 111 by the key 140, and is lolated directly below the gear wheel 113, the eccentric 115 of said gear wheel operating Hush against the upper face of said collar. Between the shaft 111 and the periphery of the clutch collar 139 is a clutch p-in socket or passage 141 into which a clutch pin 142 carried by the gear wheel 113 is adapted to drop when aligned therewith. Mounted on the upper face of the hub 113Il of the gear wheel 113 is a clutch block 143 curved toconform to the contour of the shaft and periphery of the hub 113 and held for movement away from said gear by the guide ins 144 reciprocatingly secured in the poc ets 145 formed in the hub 113a parallel to the shaft 111. The upper ends of these pockets 145 are closed by the nuts 146 (see Fig. 5) threaded into the upper ends thereof, and through which the guide pins 144 reciprocate. To normally retain the block 143 substantially flush against the upper face of the hub 113a and hence project the clutch pin 142 into the clutch pin socket 141 of the collar 139, the pins 144 are surrounded by the retractile springs 147 bearing against the nuts 146 at their upper ends and secured to the terminals of the pins at their lower ends. Hence any movement of the block 143 away from the hub 113a will be against the action of the springs 147 and these springs will pull the block toward the gear wheel 113 when the block is released for suclimovement. Above the gear wheeL 113 a fixed portion of the machine supports a depending trunnion 148 on which is loosely mounted a sleeve 149 having an operating stud 150 on one side thereof and a diametrically disposed inger 151 on the other side, the former providing a means for oscillating the sleeve I clutch block 143.4

free end 152 of the finger 151 is curved to -follow the circumference of the gear wheel hub 113al and is beveled on its upper edge (see Fig. 3)' to operate under a roller 153 projecting outwardl from the center ofthe Vhcn the sleeve 149 is uninfiuenced, the beveled end 152 of the linger 151 rests in the path of the roller 153 as it is carried by the gear'wheel 113 during its rotation, and when the roller contacts with the beveled end' 4152 it travels up. the` incline thereof, thus lifting the clutch block 143 and so positioning and holding the clutch pin 142 that it will not enterthe socket 141 of the collar 139, and the roller 153 rides on the finger 151 until the pin 142 has passed the socket 141 when it is released to allow the springs 147 to act. Hence, it is clear that shaft 111 remains stationary as long as the finger terminal 152 lies in thepath of the roller 153 and this is its normal position.

The sleeve 149 is oscilla-ted successively by the cartons or containers C to swing the finger terminal 152 from the path of move ment ofthe roller 153 Whenever a carton or 'container is in receiving position, and thus the elements of the machine operated from the shaft 111 are entirely inoperative unless a carton or container C is in receving position. For this purpose a trunnion 154 is suspended from' a Xed portion of the machine frame adjacent to the edge of the table 78 and has a sleeve 155 loosely mounted thereon which carries a stud 156 connected by the pitman 157 to the operating' stud 15G-so that as the sleeve 155 is oscillated the sleeve 149 will be similarly moved. A lug 158 carrying a spring arm 159 extends from the sleeve 155 at right angles to the stud 156, the terminal 160 of said arm 159 being bent in the direction of travel of the cartons and in the path. thereof. When a carton or container C contacts with the terminal 160 of the arm 159 the, latter is moved to the dotted line position of Fig. 1 and swings the Enger .151 out of the path of the roller 153, allowing the gear wheel 113 to operate the shaft 111 v through the clutch pin 142. In the event no carton or container C contacts with the arm 159 the machine elements operated by the shaft 111 remain passive, the roller 153 riding upon the beveled end 152 of the finger 151;. hft-ing the pin 142 from its socket 141.
